Marcos,
A suggestion to your code changes.
<?phphpinclude("class/object_def.phphp;
session_start();
// First check the $_SESSION for a previous instance of your object
if (!isisset_SESSION['session_object']))
{
$_SESSION['session_object'] = new TNTNewClasscod,$password);
}
?>
Try this first. Note I removed the 'if' statement where you were checking for a
valid object
instance. I suggest using the PHPHPunction 'is_a' and/or 'is_object'.
Start with this...
David,
This is not a correct statement "sessions work by using cookies, and cookies
can't take
phphpbjects".
In PHPHPhe session information is not pushed to the user's browser in a cookie.
Only a reference
to the session is stored in a cookie on the user's side. The actual content of
the session is
written to a file on the server.

How do you advise a script to always execute or be included before each script
is run?
I can remember reading that this was an option years ago and want to use it now
but I'm having trouble finding it in the manual.
Thanks ... Ross
